The cryptically titled Dr Golem is the third in a series: the authors, university professors who study science and technology, have previously collaborated on The Golem: What You Should Know About Science and The Golem at Large: What You Should Know About Technology. (A golem is a manmade being of Jewish legend, created from inanimate material. As such, it can be considered as having no particular intelligence of its own. It is not necessarily a monster in the way of, say, Frankenstein's monster, but rather appears to be a creature without much of a mind and certainly no soul, dumbly doing its appointed tasks.) Based on published reviews, it appears that the first two books were concerned with revealing the imperfections of science and technology.
